启用Microsoft Teams安全预览时PowerShell命令报错求助

我尝试使用PowerShell启用Microsoft Teams安全预览，执行的命令如下：

PS C:\Windows\system32> Set-TeamsSecurityPreview -Enable $true

执行后出现以下错误：

Set-TeamsSecurityPreview : The term 'Set-TeamsSecurityPreview' is not recognized as the name of a cmdlet, function,
script file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again.
At line:1 char:1
+ Set-TeamsSecurityPreview -Enable $true
+ ~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo          : ObjectNotFound: (Set-TeamsSecurityPreview:String) [], CommandNotFoundException
+ FullyQualifiedErrorId : CommandNotFoundException

我已确认以管理员身份运行命令，且安装了所需的模块和依赖项，但问题仍未解决。
